Utilization of “Instantaneous Molecule Cluster (IMC)” Hypothesis to Predict VLE in CO2 Absorption by Alkanes

Abstract—In this paper, “Instantaneous Molecule Cluster (IMC)” hypothesis is used to predict the VLE in CO2 absorption by alkanes. It is shown that the predicted values are satisfied with the experimental values (cited data) well. The results also reveal that the effect of homogenous instantaneous molecule cluster among the alkane molecules is the key factor. As carbon chain elongation, formation probability and stability of the instantaneous molecule cluster decreases and absorption capacity increases. The impact of parameter on VLE is also discussed in this paper.

Index Terms—Alkane, CO2 absorption, instantaneous molecule cluster, VLE.
